難降解含氮有機廢液之曙光－高級氧化技術在煉油廠廢液處理之應用

本研究係提出一種可處理含高濃度氨氮有機組成廢水之方法及系統，透過一種高效率方法同時催化氧化降解廢水中高濃度氨氮及有機汙染物，特別係可在不需事先去除有機懸浮固體、不需事先調整pH值、及無需經過稀釋之操作條件下，利用紫外光照活化、或微量過渡金屬催化特定之氧化劑、或藉由該兩者聯合加成之催化氧化方法，對高濃度工業廢水中的氨氮及有機毒害物進行高效率氧化降解，以達到同時降低（或完全去除）廢水中之氨氮及有機碳含量，再依實際需求進行後中和調整，使符合生物處理條件、排放水質標準或回收用水標準。藉此高效率催化氧化技術，可將煉油廢水中的烷基、芳香族、脂肪族、及雜環化合物、石油碳氫化合物等各類毒害有機物降解外，並可同時將廢水中氨氮轉化成無毒害之氮氣（N2）及硝酸氮（NO3－-N），而該反應後水中之氨氮（NH4＋-N）與硝酸氮之含量均可有效大幅降低，甚至完全去除。

The present research relates to processing organic ammonia-nitrogen wastewater; more particularly, to a high-efficiency method of simultaneously catalyzing, oxidizing, and degrading high-concentration ammonia-nitrogen and organic pollutants in wastewater, where the removal of organic suspending solids, the beforehand adjustment of pH value, and dilution are not required; and catalyzing oxidation is processed by activating a certain oxidant with ultraviolet (UV) illumination, catalyzing the certain oxidant with a trace of a transition-metal, or both of the above two operations. The benefits are to satisfy the condition and reduce the loading of biological treatment units, or even to reach the effluent standards or recycling standards. The proposed high-efficiency method could treat refinery wastewaters including alkyl compounds, aromatic hydrocarbons, aliphatic hydrocarbons, heterocyclic hydrocarbons, petroleum hydrocarbons, and so on. And the contained ammonia-nitrogen (NH4+-N) could simultaneously degrading to nitrogen (N2) and nitrate-nitrogen (NO3--N), or even to be completely removed.
